Genetic testing for Tay-Sachs disease
Tay-Sachs disease is most common in people of Central and Eastern European Jewish descent. In this community, one in 25 people are carriers of Tay-Sachs disease, compared with one in 250 of the non-Jewish population. They are not affected by the condition, and most would never know they are carriers. But, because the disorder is so devastating, doctors offer a carrier test to high-risk communities in the UK. The test results can help carriers make decisions when planning a family.
